| 摘 要： | 基于海洋统计模型,通过傅立叶变换将海浪谱从频率域转换到空间域,得到一个实时的海水高度场;然后基于现实中光线传输的规则,利用NVIDIA公司的高级语言CG对显卡编程来进行实时光照渲染,最终模拟出较为真实的海面.

| Abstract: | According to statistical ocean model, this paper presents a method that transform ocean water from the Fourier domain spectrum into the spatial domain by using FFT, and then obtains a real-time height field of ocean wave. Meanwhile, this paper discusses how to render the ocean optics through CG language by using a tool kit for programming graphics from NVIDIA. The result of exit shows that stimulating real-time ocean water surface with a photo-realistic quality can be gained. |
